The aim of the present invention is to produce a highly eificientmachine for hauling innets of a fishing craft. More particularly theinvention aims to reduce wear and tear of the-nets in the operation ofhaulingthem in and to preclude injury to the corks and leads as the sidelines are pulled by the gripping elements of the machine. I v Theinvention consists essentially in the construction and arrangement ofwhich the side lines of the nets are grasped and pulled between coactingrotary mernbers having resilient engaging faces for precluding injurytothe nets. bands or annuli of yieldable nature such as rub: her. As amatter of fact best results have been attained by utilizing pneumaticbands or tires on rigid wheels, one or both of which are driven from asuitable source of power. The wheels are mounted on substantiallyconcentric'axes in juxtaposition to each other but at a 'slightangle soas to throw a part of the bands or tires in tangential contact tocompose the yieldable gripping elements, the remainder of the wheelsrelatively diverging. By making a partial contact only between thewheels there is a breach on each side of the circumferential contactingarea, one of which sides enables the nets to feed in whilst the otherallows of its discharge after being pulled through the arc of contact.

Referring to the accompanying drawing, Figure 1 illustrates a net in themachine and shows the usual roller at the side of the fishing craft overwhich-the net runs. This View is shown in plan.

Figure 2 is a vertical sectional view taken on the line 2 2 of Figure 1.I

Figure 3 is an elevation of the rotary members and the pan for the net.

In the accompanying drawing, the hull of a fishing craft is denoted at 5which is supplied with the customary roller 5' at one side thereof overwhich the nets are drawn in hauling them in. The roller has aconventional mounting and does not form a part of the instant invention.The net pulling machine is situated in the 7 vicinity of the roller andcomprises a pair of rotary members 6 and '7, the upper one of which isdisposed in a horizontal plane and affixed to a vertical shaft andsuitably journalled within a' hollow standard 9 rising from the base 10.i
